Looks elegant and minimalist, provides good light for two pieces of sheet music, and illuminates the 88-key keyboard well. It can reach far in front of the music providing even illumination to the bottom of the page. On/Off and Dim are conveniently placed, so you don't have to reach behind like many other lights. The USB-charging port works even when the light is off. I appreciate Gravity's 5 year guarantee, especially since the LEDs are not replaceable.
As a beginner, I especially like the 6000K 'cold' light option, which provides the best contrast and readability while practising. The 3000K 'warm' light option is great for other times.
The only downside is that the black silicon finish shows fingerprints/skin-oil easily and from experience I know that silicon can be difficult to clean (tip: never use alcohol or cleaning liquids!).
